- Synthesis of polynitrostilbenes from 2,4,6-trinitro-m-xylene and 2,4,6-trinitrotoluene by a microwave-assisted solvent free method
-
A microwave-assisted method for the synthesis of polynitrostilbenes involving the condensation of 2,4,6-trinitro-m-xylene and 2,4,6-trinitrotoluene with aryl aldehydes in the presence of piperidine and silica-gel is reported. Compared with conventional methods, a shorter reaction time is required and this method has a lower environmental impact. A mechanism for the reaction is also proposed and supported by UV-Vis absorption spectroscopy.
